COMPOSITE BURNER FOR FUEL-GAS.

, gas; and it consists in certain improvements in the construction thereof, as will hereinafter fully appear.

The object of the invention is to provide a large fuelgas burner for heating furnaces, large stoves, and boilers, which can be put in at the door of the furnace in sections and then put together; and when in place one or more of its sections can be used, as the conditious may require, without affecting the other sections.

My invention is illustrated in the accompanying drawings, as follows:

Figure l is a top or plan view,with the central part of the burner broken away to show parts below. Fig. 2 is a side elevation. Fig. 3 is a transverse section on the linexm in Fig. 1, with the part 13 not shown. Fig. 4 is a perspective of one of the sections A. Fig. 5 is a perspective of one of the clasps C. r

The burner, as shown, consists of a large ring-burner formed of the segments A A A, and a disk-burner, B, mounted over the central part of the ring. When a burner of less capacity is wanted, the disk-burner may be omitted. hen a burner of still greater power is wanted, it may be composed of two rings-one larger than the other-and a diskburner; or the disk-burner may be made larger by being made of two sections. The parts of the burner I here show are made of two plates, 1) and 1), bolted together; but they may be made in any manner desired. 1 have shown the ring divided into three segments, A A A but it may be made of two or more, according to the size desired. Each segment is a complete burner in itself, with a supply-pipe independent of the others. Thus, a is the Supply-pipe for the segment A, a for A", and a? for A", and b b are the supply-pipes for the disk-burned By thus forming the burner of separate parts and providing each part with a supply-pipe, as many or as few'parts may be used as the conditions may require. Of course a furnace may be heated by supplying it with as many separate burners of small capacity as desired; but the effect will not be as perfect as when the burners are so formed as to be brought into a single body of symmetrical form, giving the effects of an integral burner. here several small round burners are brought into assemblage, as shown, for example, in

Patent No. 155,389, to Roberts, dated Septem- 6 her 29, 1874, thejets from the several burners commingle at many points; but where the several burners are made segment form, as I show them, with jets on one side only, so that when all the parts are in place the composite burner will have a uniform row ofjets around its periphery, the effect is much better, particularly when the burner is used in the fire pot of a stove or furnace, for then the jets will uniformly impinge upon the walls of the firepet.

When my burner is It] place and all the parts are in use, there will be two complete concentric rings of flame.

The construction of the several parts will be easily understood l'rom the drawings, and, as before stated, they may be constructed ac cording to any of the wellknown forms of burners.

The manner of connecting the segments of the rings together is as follows: Each segment is provided with ears 0 c in such position that they will come together when the segments are in place, to form a ring. A clasp, 0, con

sisting of a loop of metal, a, is put over the abutting ears, and a pin, 0 is driven through holes in the ears above the loop. The clasps 0 each have a section of a flange cast on them, which forms a support for the disleburner.

What I claim as new is 1. In a composite burner for fuelgas, the combination of a series of segment-formed burners with perforations or jet-openings on their curved or outer sides, connected together so as to form an integral disk or ring I00 burner, as shown, and provided with supplyburners forming a ring, and a disk-burner pipes, substantially as and for the purposes supported concentrically above said ring, and set forth. a separate supply-pipe leading to each of Said 2.
